Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

Journal of the Royal Anthropological Institute, EarlyView.
This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

Genetic introgression from commercial European pigs to the indigenous Chinese Lijiang breed and associated changes in phenotypes

Genetics Selection Evolution
Background Gene flow is crucial for enhancing economic traits of livestock. In China, breeders have used hybridization strategies for decades to improve livestock performance.

Interpreting the genomic landscape of introgression

Current Opinion in Genetics & Development, 2017
Introgression, the transfer of genetic material between species through hybridisation, occurs in many taxa and has important consequences. Genomic studies allow us to characterise the landscape of introgression across the genome, shedding light on both its adaptive benefits and the incompatibilities that help to maintain species barriers.

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

Integrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

Integrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

Integrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Genomic Investigations Unveil the Genetic Underpinnings of Environmental Adaptation in African Goat Populations

Integrative Zoology, EarlyView.
This study integrates genomics and landscape genetics to analyze African goat environmental adaptation. Analyzing 1591 samples, it finds population structure differentiates geographically into four groups, with gene flow between wild Yura goats and North Africans.

Hybridization With a Non‐Native Congener Threatens the Catalan Chub (Squalius laietanus): Optimization of a DNA‐Based Early Warning Tool

Integrative Zoology, EarlyView.
Hybridization with non‐native congeners threatens endemic freshwater fishes. Using a rapid and cost‐effective nuclear DNA assay, we detected widespread hybridization between the Catalan chub (Squalius laietanus) and the non‐native European chub (Squalius cephalus) across S.

Nest Survival Models and Genomics Illuminate Hybridisation Attempts, Guiding Culturally Informed Management to Recover a Critically Endangered Seabird

Animal Conservation, EarlyView.
Long‐term monitoring has revealed hybridisation attempts between the Critically Endangered Kuaka Whenua Hou (KWH, Pelecanoides whenuahouensis) and the abundant Kuaka (P. urinatrix). Here we use modelling based on population monitoring data in tandem with genomic data to investigate these attempts and the risk they pose to KWH recovery.

Genomic Assessment of Reintroduced African Wild Dogs Informs Conservation Translocations

Animal Conservation, EarlyView.
Few reintroduction and translocation programs incorporate genomic assessments into management planning, despite ongoing debate over how founder individuals should be selected. Here, we assess the genomic composition of reintroduced African wild dog (Lycaon pictus) populations in private reserves in South Africa, comparing them with a free‐roaming ...
